If been working on this for my daughters 4th grade homework for the last couple hours. I think the question is mistyped. It's impossible for that to work because for a rectangle to have a perimeter of 280ft it's area would be in the 1000's ft squared. Example: perimeter 140ft + 140ft + 20ft + 20 ft=280 ft
Area 140ft * 20ft = 2800ft squared.
I've tried so may other combinations without any success and don't think it's possible.
the area of a rectangleis 100 square inches. The perimeter of the rectangle is 40 inches. A second rectangle has the same area but a different perimeter. Is the secind rectangle a square? Explain why or why not.
The perimeter of rectangle A would then be 80 because 80 to 100 is 4 to 5 simplified and the area of triangle A would depend on the sides and area of rectangle B which have not been given.
yes
100 cm2
Max rectangular area for a given perimeter is a square.P = 100S = 25Area = 252 = 625 square feet

40 meters.

The smallest is just over 40 units. At 40 units it is no longer a rectangle but a square. There is no largest perimeter.
Type your answer here... give the dimensions of the rectangle with an are of 100 square units and whole number side lengths that has the largest perimeter and the smallest perimeter
Max rectangular area for a given perimeter is a square.P = 100S = 25Area = 252 = 625 square feet
It need not be a complex shape. You can have a rectangle with these properties. Just solve the two equations: 2a + 2b = 100 (for the perimeter) ab = 105 (for the area)
i think that the biggest one would be 1x100 (area) and 202 (perimeter) but i am not sure
It is 5 units * 20 units. A smaller perimeter can be attained by a square but the question specified a rectangle.
